SPECIFICATION formingpart of Letters Patent 1Y0. 755,323, dated March 22, 1904.

Application filed July 22,1903. Serial No. 166,596. (No model.)

To all whom it may cancer-h:

. in the county of Skagit, State of Washington,

' Fig. 4 is a central section at right angles to Fig;

have invented certain new and useful Improvements in Washing-Machines; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

This invention relates to washing-machines; and it has for its object to provide a construction wherein the material to be washed will be rubbed betweenthe corrugated faces of rubbers swinging in opposite directions and in different arcs, so that an efiicient operation will result.

A further object of the invention is to provide a construction such as above mentioned, in which the upper rubber will be automatically adjusted to correspond to different thicknesses of material between the rubbers.

Other objects and advantages of the invention will be understood from the following description.

In the drawings forming a portion of this invention, in which like numerals of reference indicate similar parts in the several views, Figure 1 is aperspective view showing a washing-machine closed and ready for operation. Fig. 2 is a perspective view showing the machine with the cover and upper rubber raised. Fig. 3 is a vertical section taken longitudinally through the washing-machine on the line 00 00 of Fig. 1 with the parts in operative positions.

2. Fig. 5 is a top perspective view of the upper rubber. Fig. 6 is a top perspective view of the lower rubber. spective view of the top of the machine.

Referring now to the drawings, the present washing-machine comprises abody portion 10, which is substantially semicylindrical in shape and is disposed with its curved side downwardly, the upper side of the body being open to permit of application and removal of the materials to be washed.

Secured to the flat ends of the body 10 are strips 11, which are flush with the upper ends of the body portion and which project beyond Fig. 7 is a bottom perthe curved face of the body to form handles 12. Legs 13 are secured to the ends of the body to support the latter and diverge downwardly.

j In the body 10 is disposed a lower rubber in the form of a section of the cylinder and consisting of a curved or arc-shaped bottom 13 and the sector-shaped ends 14: and 15, the upper face of. the bottom being corrugated from end to end, as shown at 16. At the central portions of the upper edges of the ends 14 and 15- are hangers 17 and 18, which are mounted upon pivots 19, which project into the body of the washer, so thatthe rubber may be swung in the plane of curvature of the bottom of the body. To swing the lower rubber, arms 19' are connected to the ends 14:

and 15 and extend through slots 20 in the body, the outer ends of these arms being pivoted to the sides20 and 21, respectively, of a two-part lever having a transverse handle 22 at the upper ends of the members. The lower ends of the members 20 and 21 are pivotedto the brackets 23 and 24, attached to legs of the body 10.

At one end of the curved bottom of the body 10 and upon the upper edges of the ends of said body is secured atransverse piece 25, to which is hinged a hollow lid 26, adapted for movement into and out of position to rest upon the upper edge of the body and close the latter.

Depending from the top of the lid or cover 26 are spaced cleats 27 and 28, and through the lid or cover is formed a slot 29, which leads to the interspace between the cleats. In the inner faces or mutually-adjacent faces of the cleats are formed vertical slots which lie opposite each other and are designed to receive the trunnions 29 on the stem 30 of the upper rubber, said stem being passed upwardly through the slot 29, where it is connected pivotally with one end of a pitman 31, the opposite end of which is bifurcated and pivoted to the members 20 and 21.

The upper rubber is also in the form of a cylindrical section and is disposed with its curved face downwardly, said curved face beformed slots 33 and 34, which are separated by the web 35, from which the stem 30 projects, the lower end portions of the cleats 27 and 28 being received in the slots 33 and 34: and being curved so that they hold the upper rubber against lateral displacement while not interfering in any way with its oscillation.

In the operation of the washing-machine a quantity of water and detergent is placed in the lower rubber, and the materials to be washed are dropped into the Water. The lid or cover of the machine is then lowered into place, so that the upper rubber rests upon the materials to be washed, the slidable engagement of the trunnions 29 in the grooves of the cleats 27 and 28 permitting the upper rubber to rest upon the materials to be washed irrespective of the thickness of the latter within certain limits, the lid or cover being fastened securely by a latch 40. The handle 22 is then grasped and rocked, causing the two rubbers to swing or oscillate in opposite directions, so that the materials are rubbed between them and thoroughly cleansed.

In practice modifications of the specific construction shown may be made, and any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.

What is claimed is 1. A washing-machine comprising a body portion, a concave rubber pivoted within the body portion, means for oscillating the rubber, a cover for the body portion having a slot therethrough, cleats depending from the sides of the slot, and having grooves in their inner faces a second rubber disposed within the body portion for cooperation with the first-named rubber, said second rubber having a stem passed through the slot, trunnions carried by the stem and lying in the slots, said second rubber having recesses in its upper face to receive the cleats to prevent lateral movement of the rubber and means for moving the second rubber upon its trunnions.

2. A washing-machine comprising a body portion, a concaved rubber pivoted in the body portion and having pivoted arms extending from the body portion, a cover for the body portion having an opening therethrough, cleats depending from the cover at the sides of the opening, a second rubber having a stem passed between the cleats and through the opening of the cover, trunnions carried by the stem, said cleats having vertical slots in their inner faces in which the trunnions are slidably and pivotally received and the second rubber having slots in its upper face in which the cleats are slidably received to hold the rubber against lateral displacement, a pivoted lever to which the arms of the first rubber are pivoted, and a pitman pivoted to the lever and to the stem of the secondrubber.

In testimony whereof I aflix my signature in presence of two witnesses.

LOUIS W. SMITH.
